BriefKit MCP Server

Engineer-grade SaaS specification generator for AI build tools.

What it does

This MCP server lets AI assistants (Claude, ChatGPT, etc.) generate structured SaaS specifications on demand. When a user asks about building a SaaS product, the AI can call these tools to produce production-ready specs.

Token efficiency

BriefKit MCP reduces token consumption by 70-85% for SaaS specification tasks on Claude Code, Cursor, and other AI assistants.

Without MCP: Claude reasons through schema, RLS, and design decisions from scratch — typically 8,000-15,000 output tokens per response.

With MCP: Claude calls structured tools that return pre-built specs in 500-1,500 tokens.

Real measurements (CRM for real estate agents):

  • Without MCP: ~11,200 tokens, 4 turns to converge
  • With MCP: ~1,800 tokens, 1 turn

If you're hitting Claude Code usage limits faster than expected on spec-heavy work, this MCP keeps spec-generation tasks under 2,000 tokens per call.

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "briefkit": {
      "command": "node",
      "args": ["/path/to/briefkit-mcp-server/dist/index.js"]
    }
  }
}
Use with Claude Code
claude mcp add briefkit node /path/to/briefkit-mcp-server/dist/index.js

Examples

User: "I'm building a CRM for real estate agents. Help me set up the database."

AI calls: briefkit_generate_database_schema with:

  • product_name: "RealEstCRM"
  • saas_type: "b2b"
  • custom_tables: ["properties", "showings", "offers", "commissions"]

Result: Complete SQL schema with 10 tables, typed columns, foreign keys, indexes, and security baseline.

User: "Generate RLS policies for my SaaS. I have profiles, orders, and payments tables with Owner and Member roles."

AI calls: briefkit_generate_rls_policies with:

  • tables: ["profiles", "orders", "payments"]
  • roles: ["Owner", "Member"]

Result: Complete RLS SQL — payments are server-write-only, profiles role is immutable, owners see own data only.
